IMPROVEMENT IN DRAFT-EQUALIZING AATTACHMENTS.

Speccation'forming part of Letters Patent No. 39,517, dated August 11,1863.

To all whom it may concern:

Be it known that I, `Jninns WILKINSON, of Prophetstown, in the county ofWhiteside and State of Illinois, have invented a new and ImprovedDraft-Equalizing Attachment for a Reaper and other Wheel-Vehicles 5 andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making la part of this specification, in Which- Y,

. Figure 1 is a plan or top view of my inventon; Fig. 2, a transversesection of the saine;

` Fig. 3, a detached View ofthe neck-yoke.

Similar letters of reference indicate correfsrondingparts in the severalgures.

The invention consists in' a novel 'arrangement of whiftletrees,draft-pole, double-tree, neck-yoke, and traces, as hereinafter fullyshown and described, whereby the draft of the animalsis rendered equalor the horses made to p ull equally in drawing the reaper or othervehicle along.

The invention is more especially designed f for reapers, but may beadvantageously applied to other vehicles.

To enable those skilled in the art to fully understand and construct myinvention, I

' will proceed to describe it.

A represents the draft-pole of a reaper, and B a double-tree, attachedthereto, as usual, by a central bolt, a. To each end of the vdoubletreeC there are attached by bolts c two wifetrees, D D'-one at the top andthe other to the under side of the double-tree, as shown in Fig. 2.On'the front end of the draft-pole A there is fitted a neck-yoke,-E, towhich the ybreast-straps ofthe wheel-horses are attached.

F F' represent the traces of I the leaders orf l front horses, one ofthe traces, F, of each'front horse being attached to the upperwhiftletrees, D, and the other traces, F, of the same horses beingattached tothe lower whiletrees, D.

G G' represent the tracesot the wheelhorses, one, G, of each horse beingattached to the upper whiftletrees, D, and the other, G', to the lowerwhiffletrees, D', as shown clearly in Fig. 1. By this arrangement itwill be seen that the traces lof the two nearf as well as l those of thetwo oft`, horses are connected through the medium of the two pairs ofwhif- `letrees D D', and the draft of said horses will consequently beequalized.' The traces of the leaders or front horses pass through theneckyoke E. The double-tree B operates in the usual way, and servesto'equalize the draft between the near and o' horses. The invention is adecided improvementfor four-horse
